WINDOW CONSTRUCTION.

Specification of Letters Patent.

Patented Apr. s, i919.

Original application led Uctober 5, 1908, Serial No. 456,289. Divided and this application iled November y l 30, 1914. Serial N0. 874,751.

To all who@ may concern: Be it known that I,'GE0RGE H. Fonsr'rii, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented vcertain new and'usefulImprovements in Window Constructions,

i of which the following is a specification, the

same being a division of my copendin application, Serial No. 456,289, filed Octo er 5,

The invention relates to improvements in window constructions, some of which are more especially, although not exclusively,

. applicable to car windows; and the invention consists in the several features of improvementin a window construction, all as hereinafter-'described and more particularly pointed out inthe claims. l

`The invention will be readily understood when considered in connection with the accompanying drawings, which illustrate i one practical embodiment thereof, and in which- Figure 1"`is a transverse section through a sash member illustrating the invention; and 2`is a perspective view showing "the same invention in modified'form.

Having reference to Fig. 1 of the drawing the sash member 11 is shown as of tubular construction, the integral walls of which overlap marginally and are additionally secured by rivets 12. The material of the sash member is so shaped as to provide a fixed rigid laterally supporting bead 13 and a transverse tie wall forming a fixed rigid shelf' or ledge 14 for supporting the glass in the plane thereof. Most of the commercial glass used for glazing purposes is more or less irregular; and a rigid' glazing strip, when screwed home, will frequently result in a fracture or break of the glazing. A glass-holding means, therefore, possessing some transverse resiliency or yieldability, is highly desirable. In Fi 1, 15 designates a removable strip of suita le U-form made of elastic material, with the sides thereof bent or sprung inwardly. TheA margin :of the glass is inserted between the free upper edges of this strip and, to form acushion seat for forming spring fingeis`17 which pass into recesses or apertures 18 in the inner wall of the frame member and at their inner` edges its marginal portions overlapped and inter-l locked and united in any suitable manner as by brazing-at 20. In this case also a fixed glass supporting bead is provided lat 20 and a tie Wall and glass supporting ledge or shelf at 21.v i

Here the pane 22 is cushioned on one side by a rubber or other yielding strip confined between one side ofi the glazing and the inner wall ofthe bead"l20g while thev opposite sibde of the glazing is pressed upon by remova e ous slieet metal strip 23 which has its lower edge notched to provide a series of fingers 24 passingthrough an apertured countersunk portion or recess 25 of the sash member and secured by suitable means at 26 to the opposite wall of the latter. forms shown in Figs. 1 and 2, the glazing strip is readily removable, in Fig. 1 by simply pulling out the fingers 17, and in 2y by depressing the strip 2,3; also the removable glazing means yieldingly supports the glass laterally by reason of the engagement of its lower edge and its bearing in its medial portion against the wall of the recess 18 or 25.

It will be evident to those skilled in the art that the various improvements hereinabove described arc capable of considerable modification asv to'details without departing from the invention or sacrificing any of the advantages secured thereby. Hence, I do not limit the invention to the particular forms shown, except to the extent clearly indicated in specific claims.

I claim:

1. In sash construction, the combination In all the Glazing" means in ,the formv of a continu.

recess of the sash, the strip having its upper portion arranged as a lateral support for the glass margin and fulcrumed in its medial portion upon a wall of Vthe recess with its lower portion extending into the recess and .frictonally interlocked with a portion of 'the sash member to preclude accidental dis-A placement.

2. In sash construction, the combination with a tubular sash member havin its side walls held against spreading at t e inner edge of the sash by a transverse wall serving as a seat for the glass and providing an integral bead or abutment at oneside of the glass seat for laterally supporting the glass along one margin thereof and havin formed therein a recess along the'other si e of the glass seat, of removable glazing means comprising a spring strip seated within the recess of the sash, the strip having its upper portion arranged as a lateral support for the glass margin and fulcrumed in its medial portion y,upon a wall ofthe recess with its lower portion extending into the recess and offset into interlocked engagement with a portion of the sash member to preclude disvplacementl of the said strip without temporary distortion thereof.

3. In sash construction, the combination with a sash member having its side walls held against spreading at the inner edge of the sash by a transverse wall, the sash member providing a seat for the glass and an integral bead or abutment at one side of the glass seat, and a recess along theA other sidel of the glass seat, `of removable lazing means comprising a strip seated wit in the recess of the sash, the strlp having its upper portion arrangedf'as a lateral support for' the glassmargin and fulcrumed in vits medial portion upon awall of the recess with its lower portion extending into the recess and frictionally interlocked with a portion of the sash member to preclude accidental displacement, and spring means disposed between the glass and thel lateral support therefor to exert constant outward pressure of theglass margin and fulcrumed in its medial portion upon awall of the recess with its lower` portion extending into the recess and offset into frictional mterlocking engagement with a portion ofthe sash member to preclude accidental displacement, and spring means disposed between the yedge of the glass and its seatand extending on both sides of the glass margin between the glass andthe integral support on one side and the upper edge of the removable glazing strip on the other side, whereby to permit the strip to yield out of engagement with the sash and to be removed from the recess.

In testimony whereof I have hereunto signed my name in the presence of two subscribing Witnesses. GEORGE H. FORSYTH. Witnesses:
